Detailed Description
PackageStructure plasma/packagestructure.h <Plasma/PackageStructure>
A description of the expected file structure of a given package type
PackageStructure defines what is in a package. This information is used to create packages and provides a way to programatically refer to contents.
An example usage of this class might be:
PackageStructure structure;
structure.addDirectoryDefinition("images", "pics/", i18n("Images"));
QStringList mimetypes;
mimetypes << "image/svg" << "image/png" << "image/jpeg";
structure.setMimetypes("images", mimetypes);
structure.addDirectoryDefinition("scripts", "code/", i18n("Executable Scripts"));
mimetypes.clear();
mimetypes << "text/\*";
structure.setMimetypes("scripts", mimetypes);
structure.addFileDefinition("mainscript", "code/main.js", i18n("Main Script File"));
structure.setRequired("mainscript", true);
One may also choose to create a subclass of PackageStructure and include the setup
in the constructor.
Either way, PackageStructure creates a sort of "contract" between the packager and the application which is also self-documenting.
Method Documentation
Default constructor for a package structure definition
@arg type the type of package. This is often application specific.
Adds a directory to the structure of the package. It is added as a not-required element with no associated mimetypes.
- Parameters:
-
key used as an internal label for this directory path the path within the package for this directory name the user visible (translated) name for the directory
Adds a file to the structure of the package. It is added as a not-required element with no associated mimetypes.
- Parameters:
-
key used as an internal label for this file path the path within the package for this file name the user visible (translated) name for the file
| bool allowExternalPaths | ( | self ) |
- Returns:
- true if paths/symlinks outside the package itself should be followed. By default this is set to false for security reasons.
| QString contentsPrefix | ( | self ) |
- Returns:
- the prefix inserted between the base path and content entries
| createNewWidgetBrowser | ( | self, | ||
| QWidget | parent=0 | |||
| ) |
When called, the package plugin should display a window to the user that they can use to browser, select and then install widgets supported by this package plugin with.
The user interface may be an in-process dialog or an out-of-process application.
When the process is complete, the newWidgetBrowserFinished() signal must be emitted.
- Parameters:
-
parent the parent widget to use for the widget
| QString defaultPackageRoot | ( | self ) |
- Returns:
- preferred package root. This defaults to plasma/plasmoids/
| [const cha] directories | ( | self ) |
The directories defined for this package
| QStringList entryList | ( | self, | ||
| QString | key | |||
| ) |
Get the list of files of a given type.
@arg key the type of file to look for
- Returns:
- list of files by name
- Since:
- 4.3
| [const cha] files | ( | self ) |
The individual files, by key, that are defined for this package
Installs a package matching this package structure. By default installs a native Plasma.Package.
- Parameters:
-
archivePath path to the package archive file packageRoot path to the directory where the package should be installed to
- Returns:
- true on successful installation, false otherwise
| bool isRequired | ( | self, | ||
| QString | key | |||
| ) |
- Returns:
- true if the item at path exists and is required
| Plasma.PackageStructure.Ptr load | ( | QString | packageFormat | |
| ) |
Loads a package format by name.
@arg format If not empty, attempts to locate the given format, either from built-ins or via plugins.
- Returns:
- a package that matches the format, if available. The caller is responsible for deleting the object.
| Plasma.PackageMetadata metadata | ( | self ) |
- Returns:
- the package metadata object.
| QStringList mimetypes | ( | self, | ||
| QString | key | |||
| ) |
- Returns:
- the mimetypes associated with the path, if any
| newWidgetBrowserFinished | ( | self ) |
Emitted when the new widget browser process completes.
- Signal syntax:
QObject.connect(source, SIGNAL("newWidgetBrowserFinished()"), target_slot)
| QString path | ( | self ) |
- Returns:
- the path to the package, or QString() if none
| pathChanged | ( | self ) |
Called whenever the path changes so that subclasses may take package specific actions.
| read | ( | self, | ||
| KConfigBase | config | |||
| ) |
Read a package structure from a config file.
| [const cha] requiredDirectories | ( | self ) |
The required directories defined for this package
| [const cha] requiredFiles | ( | self ) |
The individual required files, by key, that are defined for this package
| QString servicePrefix | ( | self ) |
- Returns:
- service prefix used in desktop files. This defaults to plasma-applet-
| setAllowExternalPaths | ( | self, | ||
| bool | allow | |||
| ) |
Sets whether or not external paths/symlinks can be followed by a package @arg allow true if paths/symlinks outside of the package should be followed, false if they should be rejected.
| setContentsPrefix | ( | self, | ||
| QString | prefix | |||
| ) |
Sets the prefix that all the contents in this package should appear under. This defaults to "contents/" and is added automatically between the base path and the entries as defined by the package structure
@arg prefix the directory prefix to use
| setDefaultMimetypes | ( | self, | ||
| QStringList | mimetypes | |||
| ) |
Defines the default mimetypes for any definitions that do not have associated mimetypes. Handy for packages with only one or predominantly one file type.
- Parameters:
-
mimetypes a list of mimetypes
| setDefaultPackageRoot | ( | self, | ||
| QString | packageRoot | |||
| ) |
Sets preferred package root.
| setMimetypes | ( | self, | ||
| QString | key, | |||
| QStringList | mimetypes | |||
| ) |
Define mimetypes for a given part of the structure The path must already have been added using addDirectoryDefinition or addFileDefinition.
- Parameters:
-
key the entry within the package mimetypes a list of mimetypes
| setPath | ( | self, | ||
| QString | path | |||
| ) |
Sets the path to the package. Useful for package formats which do not have well defined contents prior to installation.
| setRequired | ( | self, | ||
| QString | key, | |||
| bool | required | |||
| ) |
Sets whether or not a given part of the structure is required or not. The path must already have been added using addDirectoryDefinition or addFileDefinition.
- Parameters:
-
key the entry within the package required true if this entry is required, false if not
| setServicePrefix | ( | self, | ||
| QString | servicePrefix | |||
| ) |
Sets service prefix.
| QString type | ( | self ) |
Type of package this structure describes
Uninstalls a package matching this package structure.
@arg packageName the name of the package to remove @arg packageRoot path to the directory where the package should be installed to
- Returns:
- true on successful removal of the package, false otherwise
| write | ( | self, | ||
| KConfigBase | config | |||
| ) |
Write this package structure to a config file.
